Patented Dec. 8, 1931 UNITED STATES PATENT OFFICE? MAX EMIL PODGORSKI AND LOUISE M. SOLDEN, OF MILWAUKEE, WISCONSIN DEVICE FOR EXTENDING ADJUSTABLE WINDOW SCREENS Application filed August 17, 1931. Serial No. 557,708.

I drawings is a full, clear and exact description. The objects of the invention are to provide a device by means of which the members of theadjustable screen may be moved toward each other and secured in juxtapositlon, when such screen nay be placed in a window frame, whereupon, by finger pres- 7 sure upon a trigger, the operative parts of the mechanismcause the slidably adjustable screen elements to be quickly and automatically extended within the opposing surfaces of such window frame. F

, W'ith these and other objects in' view, the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part 'of 7 :this specification.

Figure 2 a side view and Figure 3 In the drawings, Figure 1 is a top view,

a transverse, sectional, left-end view on' the line,

AA of said Figure 2. 4 Similar letters refer near end of this cylindrical member, D, is

telescoped within the opposing end of the hollow cylindrical member, A, against the helical spring, S withinsaid hollow cylindrical member, A. IVhen hollow cylindrical member, D, is used, said spring, S may e tend into the same, as illustrated in Figures 1 and 2. The opposite, further ends, E and F, respectively of each, said cylindrical meinbers, A and are drawn and flattened. Thereby a stop is formed for the opposite ends of said spring, S, which is compressed by telescoping said cylindrical member, D, within said hollow cylindrical member, A. A hole, a is provided in said flattened end, E of said cylindrical member, D. A hole, I)

is likewise provided in said flattened end, F, of said hollow cylindrical member, A. These holes, a and b in the further flattened ends of each said cylindrical members, D and A, respectively, are designed to allow of fastening the same with wood screws, or other suitable means to the opposite sides of an adjustable screen.

' l/Velded, or otherwise secured to the bottom of said cylindrical member, A is the base, B designed to furnish a flat surface for resting upon one of the extensible elements of such screen when the device is applied thereto as described. The strap, C passes underneath and around the sides of said base, B, near the inside end thereof, and the ends of said icured to the top and side surfaces near the inside end of said cylindrical member, A. Near the inside end of said handle, G and at a distance from the line of junction thereof with the top surface of said cylindrical memher, A, the bearing pin, I passes through a suitable, transverse hole in said handle, G. The shank of the catch lever, H is provided with a similar hole, where it is pivoted upon said pin, I against said handle, G. The member, J I furnishes lateral guidance for the other side of the shank of said catch lever, H when said bearing pin is passed through a corresponding hole in said member, J and the opposite ends of said bearing pin, I are riveted over, or otherwise secured against the outside surfaces of said respective members, G and J, so that the shank of said catch lever is oscillable between them. The top end of the spring, K passes around, and is held in place by a lug on the lower end of the shank of said catch lever, H, as shown in Figure 2; or, the top end of said spring, K may be otherwise secured to the lower end of the shank of said catch lever, H. The bottom end of said spring, K is secured by suitable means upon, or into the top surface of said cylindrical member, A, underneath the shank of said catch lever, H, so that the distensive action of said spring, K normally a n from the1actionofsaid spring,

7 From the foregoingdescription, it W'ill'be forces the catch hook, (Z of said lever, H, into contact along the longitudinal center on the s top surface of said cylindrical member, D. Thereupon, Whensaid cylindrical member, D is 'telescoped into said hollow cylindrical member, A to a sufiicient extent, said catch shook, d of said lever, H will engage said hole, 7L, provided ator that vpurposeyas :aiioresaidfin the center of thetop, near the flattened end, E, of said cylindrical member, I). When the trigger, tof said catch llever, is compressed against the action of said spring, K, said catch hoolnr'l will be lifted "from said hole, It, thus allowing the distensive action of said spring, S to force said cylindrical member, D .outof its .telescoped position within said hollow cylindrical member A. Aguard, L mayibe secured by welding-or ot'her means, at its :top end to the lower sur face of the grip part of the handle, it} a'tiitsjbottom end :to the-upper sunfaceof said cylindrical member, A, opposite .that sideloif the spring, K which is nearer the center-of the length of said handle, "G, for protect Qing: the hand of a person .usingthe device evident that :when this device is secured, Jat and F, respectively, to the-opposite sides of an, adjustable screen comprising several elements, which :from .a superimposed zrela tion, :the one .to the other, i may be extended within guides to a predetermined :relation to each other, a simple, efiicient means v-isiaf-v forded for holding-xthese elements of such screen in fixed, collapsed relation, when the catc'h'ihook, il engages said hole, .h insaid Icylindr'ical pmeniber, Then, after such screen, with this .device so applied thereto, 'is,.p'ilaced Iinposition within a .window [frame .to which suchscreenkand device are suited, by applying pressure upon the-trigger, t with aQfingenof the-'handlholding the handle, the .catch .hook, il vwill 'be released from jsaidrhole, "h.
